SergioDeNice Posted April 8, 2021 Report Share Posted April 8, 2021 Hi there, I bought an old duke gamepad which unfortunately has a problem with its left thumbstick. The thumbstick feels OK and can move in any direction but it always sends the same x-axis signal : full right i.e. maximum positive value (tested with TestLaunch). What could be the cause? Bad cable? Bad solder? Bad joystick mechanism? Something else? Please advise! TIA Serge Quote Link to comment Share on other sites More sharing options...
Crossfader Posted April 10, 2021 Report Share Posted April 10, 2021 (edited) I think the potentiometer is dirty or defective. You can desolder the poti and clean the contact surface with IPA. Or you can replace the complete thumbstick with a new one from aliexpress. The 360 thumbsticks fit in the Xbox S controller. If it fits in the duke controller can i not guarantee.

BlackIvan Posted April 10, 2021 Report Share Posted April 10, 2021 I opened my duke controller just few weeks ago because I had a similar problem with the left stick. I'm not 100% sure but I would bet it has the same sticks as the S controller. Actually this kind of problems could depend even from some kind of corrosion or dirt on the main board, so I'd suggest to give it a really good clean before taking out the soldering iron.

SergioDeNice Posted April 10, 2021 Author Report Share Posted April 10, 2021 Yep the potentiometer is the same as in the 360 gamepd. I tried desoldering just the side bit (i.e. the X pot) and soldering another one in place (I had spare parts lying around) but I ended f*cking up the board because I suck at soldering Thanks for your answers anyway.
